The video palette has changed.
Parameters
- lParam1
- Zero.
- lParam2
- Zero.
Remarks
This event notification is sent to the application and the filter graph manager. Whenever a video renderer detects a palette change in the stream, it should send the EC_PALETTE_CHANGEDnotification to the filter graph manager. The DirectShow video renderers detect whether a palette has really changed in dynamic format or not. The video renderers do this not only to filter out the number of EC_PALETTE_CHANGEDnotifications sent, but also to reduce the amount of palette creation, installation, and deletion required.
For information on how to use this event code, see CBaseFilter::NotifyEvent.
